Lake-effect Snow and Whiteout Conditions in the Great Lakes Region; Below-average Temperatures in the East

Heavy lake-effect and lake-enhanced snow will persist downwind of the Great Lakes and produce some whiteout conditions that could cause difficult travel conditions. A coastal low will produce moderate to heavy snow over parts of southern and eastern New England into the afternoon. Below average temperatures are expected across the eastern U.S., particularly with chilly morning temperatures. Read More >

Overview

A potent low pressure system has moved off to the northeast while high pressure builds in from the west. The area between these two systems is where all the wind is located, ushering in a much colder air mass on brisk northwest winds. Any lingering snow will end by noon with clearing skies expected by late afternoon or early evening. Lows tonight will bottom out in the lower to mid 20s, and we may even see some teens for lows Sunday night into Monday morning. Highs today and Sunday will be in the lower to mid 30s with the brisk northwest winds becoming light by Sunday afternoon.
